Technical Field

[0001] The utility model relates to a vehicle-mounted mobile integrated crossing frame, belonging to the technical field of crossing frames. Background Art

[0002] A crossing frame is a device that protects the conductor and the objects below it. In the construction of power transmission lines, it is often necessary to cross various obstacles such as roads, railways, broadcasting lines, power lines, etc. In order to prevent the conductor from being damaged and not affect the safe operation of the objects being crossed, a crossing frame must be set up at these crossings before laying out the wires to allow the conductors to pass safely and smoothly. The crossing frame is made of insulating materials such as insulating steel pipes, bamboo sticks, and wooden sticks.

[0003] During the installation of a traditional spanning frame, a spanning frame needs to be built above the object to be spanned according to its height. The spanning frame is usually constructed by multiple workers, and insulating steel pipes, bamboo sticks and other pillars are fixed to form a large spanning frame. The construction process is relatively complicated and requires a lot of manpower and time. In addition, if the height of the object to be spanned is high, the required height of the spanning frame is also high. There are safety hazards for workers working at high altitudes, which is not conducive to rapid construction.

[0004] To this end, the invention patent with the Chinese patent authorization announcement number CN114069469B discloses a vehicle-mounted mobile integrated crossing frame and its use method, including a transport seat, a support, a crossing frame body, a locking mechanism, and a retractable bracket mechanism. The top of the transport seat is rotatably connected to a rotating seat, and a slide groove is provided at the top of the rotating seat. The support is slidably connected to the rotating seat through the slide groove. The crossing frame body is placed on the top of the support. A locking mechanism is installed between the support and the transport seat, and a retractable bracket mechanism is installed at the bottom of the transport seat. The position of the crossing frame body is rotated by the rotating seat to quickly align the crossing frame base with the boom seat of the car, and the crossing frame base is brought close together with the boom seat of the car by moving the support, so that the entire construction process is simple and easy to operate. Compared with the traditional installation method of the crossing frame, the installation method of the vehicle-mounted mobile integrated crossing frame described in the above invention is more convenient and quick. However, the following problems still exist in its actual use:

[0005] The main body of the crossing frame can be fixedly connected to the boom of the truck crane through a fixing ring and a bolt structure. The bolt connection method requires the user to carry the corresponding bolt connectors and connection tools with the vehicle. If the user forgets, the main body of the crossing frame cannot be installed on the boom. At the same time, the bolt connection method also has the problems of long connection time and high labor cost during operation. Therefore, improvement is needed. Utility Model Content

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example: Please refer to Figures 1 to 4 The present embodiment provides a vehicle-mounted mobile integrated crossing frame, including a crossing frame body, the crossing frame body including a crossing frame base 1 and an umbrella column 2, an umbrella rib 3 and an umbrella opening motor 4 arranged on the crossing frame base 1. When the umbrella opening motor 4 is working, the umbrella rib 3 can be unfolded on the crossing frame base 1, so that construction personnel can carry out the required transmission line construction work.

[0025] In this embodiment, a connecting groove 5 is opened inwardly on the side wall of the crossing frame base 1 away from the umbrella column 2. The structure of the connecting groove 5 is adapted to the hook 6 of the external boom so that the hook 6 can be inserted into the connecting groove 5. At the same time, the structure of the connecting groove 5 should not be too large compared with the hook 6, so as to avoid a large space for the hook 6 to move horizontally to the left and right in the connecting groove 5, thereby ensuring the stability of the subsequent hook 6 when hoisting the crossing frame body.

[0026] A fixing assembly for fixing the hook 6 inserted into the connecting groove 5 is provided in the connecting groove 5, and the fixing assembly includes a clamping cylinder 7, which is provided at both sides of the connecting groove 5. A first slide groove 8 is provided on one side of the connecting groove 5, and a second slide groove 9 is provided on the other side of the connecting groove 5. A first slider 10 is slidably connected in the first slide groove 8. The telescopic rod end of the clamping cylinder 7 on the corresponding side extends into the first slide groove 8 and is connected to the side wall of the first slider 10 away from the connecting groove 5, so as to push the first slider 10 to slide in the first slide groove 8. A first fixing rod 11 is provided on the side wall of the first slider 10 close to the connecting groove 5. A second slider 12 is slidably connected in the second slide groove 9. The telescopic rod end of the clamping cylinder 7 on the corresponding side extends into the second slide groove 9 and is connected to the side wall of the second slider 12 away from the connecting groove 5, so as to push the second slider 12 to slide in the second slide groove 9. A second fixing rod 13 is provided on the side wall of the second slider 12 close to the connecting groove 5. The first fixing rod 11 and the second fixing rod 13 can enter into the connecting groove 5 and dock together under the action of the corresponding side pressing cylinder 7 , and the docked first fixing rod 11 and the second fixing rod 13 are located in the hook body of the hook 6 inserted into the connecting groove 5 .

[0027] In this embodiment, a docking groove 14 is provided inwardly at the end of the first fixing rod 11 away from the first slider 10 , and the diameter of the docking groove 14 is adapted to the diameter of the second fixing rod 13 . The second fixing rod 13 is inserted into the docking groove 14 to dock with the first fixing rod 11 .

[0028] Through the above-mentioned arrangement, when it is necessary to lift the main body of the crossing frame for the required power transmission line construction, the construction personnel insert the hook 6 on the external lifting arm into the connecting groove 5, and then the construction personnel control the clamping cylinders 7 on both sides to start working. The clamping cylinders 7 on both sides push the first slider 10 and the second slider 12 to make the first slider 10 and the second slider 12 move close to each other, so that the first fixing rod 11 and the second fixing rod 13 can be inserted into the hook body of the hook 6 and docked, that is, the second fixing rod 13 is inserted into the docking groove 14 in the first fixing rod 11. At this time, the external lifting arm pulls the first fixing rod 11 and the second fixing rod 13 through the hook 6 to lift the main body of the crossing frame. After that, the construction personnel control the umbrella opening motor 4 to make the umbrella ribs 3 unfold, and then the required power transmission line construction can be carried out. Compared with the bolt connection in the prior art, it has the advantages of fast connection and reduced labor intensity of construction personnel.

[0029] In order to prevent the first fixing rod 11 and the second fixing rod 13 from interfering with the action path of the hook 6 when the hook 6 is inserted into or out of the connecting groove 5, in this embodiment, the depth of the first slide groove 8 is set to meet the first fixing rod 11 can be fully retracted into the first slide groove 8 under the action of the corresponding side clamping cylinder 7, and the depth of the second slide groove 9 is set to meet the second fixing rod 13 can be fully retracted into the second slide groove 9 under the action of the corresponding side clamping cylinder 7. Through the above-mentioned setting, when the hook 6 needs to be inserted into the connecting groove 5 or when the hook 6 needs to be taken out of the connecting groove 5 after the construction work is completed, the construction personnel start working by controlling the clamping cylinders 7 on both sides to make the first slider 10 and the second slider 12 move away from each other, so that the first fixing rod 11 is fully retracted into the first slide groove 8 and the second fixing rod 13 is fully retracted into the second slide groove 9, and then the construction personnel can smoothly insert the hook 6 into the connecting groove 5 or take the hook 6 out of the connecting groove 5.

[0030] In order to further fix the hook 6 in the connecting groove 5 and avoid the subsequent unstable lifting due to the lateral movement of the hook 6 in the connecting groove 5, in this embodiment, a clamping assembly 15 is also provided on the side wall of the first slide groove 8 and the second slide groove 9 close to the connecting groove 5. The clamping assembly 15 includes a steel gasket 151 and a rubber gasket 152. The number of steel gaskets 151 and rubber gaskets 152 is multiple, and the number of steel gaskets 151 and rubber gaskets 152 can be set according to actual conditions. The steel gaskets 151 and rubber gaskets 152 are alternately stacked. The purpose of the alternating stacking is that if all rubber is used, the material is too soft and the rebound is slow, which may fail to ensure the required clamping and fixing effect. By blocking and arranging steel gaskets between the rubber gaskets 152, the soft elasticity of the rubber gaskets 152 can be suppressed and its toughness and elasticity can be improved to meet the subsequent clamping requirements. The setting of the clamping components 15 on both sides satisfies that they can be clamped against the corresponding side walls of the hook 6 inserted into the connection groove 5 when the first fixing rod 11 and the second fixing rod 13 are connected. When the clamping components 15 on both sides are clamping against the corresponding side walls of the hook 6, the rubber gasket 152 will deform accordingly to adapt to the width of the hook 6, and the steel gasket 151 can provide the required support for the clamping and fixing work. Through the above-mentioned setting, the setting of the clamping components 15 on both sides can clamp and fix the hook 6, thereby preventing the hook 6 from moving horizontally in the connection groove 5, and further ensuring the stability during subsequent lifting.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
